It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0034] Figure 1 A schematic diagram showing the arrangement of the fire-fighting airbag and the materials to be transported provided by an embodiment of the present utility model is shown; Figure 2 A schematic diagram showing a firefighting airbag provided by an embodiment of the present invention in a folded state; Figure 3 A schematic diagram showing a firefighting airbag provided by an embodiment of the present utility model in an open state; Figure 4 A schematic diagram showing a firefighting airbag provided by an embodiment of the present invention wrapped around materials to be transported. Figures 1-4 This embodiment provides a firefighting airbag and a vessel. The vessel includes a hull and the firefighting airbag provided in this embodiment. The hull is provided with multiple material placement locations for transported materials. In this embodiment, the materials to be transported are specifically electric vehicles. Each material placement location is provided with a firefighting airbag, which is specifically arranged below the electric vehicle.

[0035] Reference Figure 2The fire airbag includes a box 100, a fireproof airbag body 200, a gas generator, a temperature sensor 300 and a control system. The gas generator is arranged in the box 100 and connected to the fireproof airbag body 200, and can inflate the fireproof airbag body 200. The fireproof airbag body 200 can be folded in the box 100, and can also be inflated and opened by the gas generator to rush out of the box 100 and wrap around the material 10 to be transported at the material placement location. The temperature sensor 300 is arranged on the box 100 and is communicatively connected to the control system. The temperature sensor 300 can sense the temperature of the material placement location to be transported, and the control system can control the operation of the gas generator based on the temperature of the material placement location to be transported sensed by the temperature sensor 300. When the temperature of the material placement location to be transported reaches the trigger temperature, the control system controls the gas generator to inflate the fireproof airbag body 200. In this embodiment, the trigger temperature can specifically be 80°C.

[0036] The gas generator can inflate the fireproof airbag body 200, causing it to expand and wrap around the transported material, isolating it from the air and controlling the fire. The fireproof airbag body 200 can also separate the fire-affected material from other materials to prevent the fire from spreading. If a material catches fire, as the temperature on the hull rises, the temperature sensors 300 of the fireproof airbags located at each material placement location will sense it. Once the temperature at each material placement location reaches the trigger temperature, the corresponding fireproof airbag body 200 will inflate and expand to wrap around the unburned material to prevent it from heating up further.

[0037] The temperature sensor 300 can quickly sense the temperature of the material placement location. The control system can be triggered based on the temperature signal from the temperature sensor 300 to quickly control the operation of the gas generator. In this embodiment, the control system can specifically be a PLC controller that can be integrated into a vessel. The specific structure and principles of this control system are not detailed here.

[0038] Reference Figure 3 and Figure 4 The fireproof airbag body 200 includes a wrapping portion 210 and a relief portion 220. The wrapping portion 210 can wrap around and contact the fire location of the transported material 10, while the relief portion 220 can avoid the unfired location of the transported material 10. This arrangement can improve the fit of the wrapping portion 210 against the fire location, thereby ensuring the insulation effect of the wrapping portion 210 on the fire location.

[0039] In this embodiment, the transported material 10 is provided with batteries and wheels at its bottom. Multiple escape portions 220 are provided corresponding to the wheels, enabling them to avoid the vehicle's wheels. Multiple escape portions 220 are positioned at the corners of the fireproof airbag body 200, forming a cross-shaped wrapping portion 210. When the fireproof airbag body 200 is inflated and deployed, the wrapping portion 210 can abut and wrap around the bottom of the battery and the side of the vehicle, reliably isolating the battery installation location where a fire could occur.

[0040] Reference Figure 2 The gas generator is disposed inside the bottom of the box 100. A top cover is disposed on the top of the box 100. The top cover is rotatably disposed on the top opening of the box 100 and can close or open the top opening of the box 100. The fireproof airbag body 200 is folded and disposed within the box 100. The fireproof airbag body 200 can inflate and push open the top cover.

[0041] Specifically, the top cover can be opened to be parallel to the side of the box body 100. Through the above arrangement, it is possible to avoid the top cover obstructing the fireproof airbag body 200 during its inflation and deployment, thereby prolonging the time required for the deployment of the fireproof airbag body 200 and causing the problem that the fire cannot be controlled in time.

[0042] More specifically, the fireproof airbag body 200 can be made of a high-temperature resistant flexible material with a lower heat resistance limit of 1200° C. In this embodiment, the fireproof airbag body 200 can be made of ceramic fireproof cloth, high-silica fireproof cloth, or basalt fiber fireproof cloth.

[0043] More specifically, the gas generator is capable of generating non-combustible gas and delivering the non-combustible gas into the fireproof airbag body 200. In this embodiment, the non-combustible gas is specifically nitrogen. The gas generator may include a pyrotechnic device and a sodium azide containing device. When the control system receives a trigger temperature signal from the temperature sensor 300, it can send an electric current stimulus to the pyrotechnic device, thereby causing the gunpowder or explosive inside the pyrotechnic device to burn or explode, releasing energy. This energy can be converted into mechanical energy, causing the box 100 to vibrate violently, thereby triggering a chemical reaction of the sodium azide in the sodium azide containing device. The sodium azide will generate a large amount of nitrogen within 0.1s and fill the fireproof airbag body 200.

[0044] Preferably, the fireproof airbag body 200 is provided with an insulation layer that expands upon heating to form a fire-extinguishing foam layer. The insulation layer also contains a gas generating agent, which can be at least one of dodecafluoro-2-methyl-3-pentanone, ammonium bicarbonate, or carbon tetrachloride. The gas generating agent has a gas generating temperature of 50-80°C and decomposes reversibly.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
